  Strong interaction - Wikipedia, the free encyclopedia
The strong interaction or strong force is today understood to represent the interactions between quarks and gluons as detailed by the theory of quantum chromodynamics.
The strong force is the fundamental force mediated by gluons, acting upon quarks, antiquarks, and the gluons themselves.
This force was postulated to overcome the electric repulsion between protons in the nucleus, and for its strength (at short distances) it was dubbed the "strong force".

Nuclear weapons are often described as either fission or fusion devices based on the dominant source of the weapon's energy.
This form of radioactive contamination is known as nuclear fallout and poses the primary risk of exposure to ionizing radiation for a large nuclear weapon.
Nuclear weapons are relatively inefficient in their use of fissionable material, and much of the uranium and plutonium is dispersed by the explosion without undergoing fission.

Electromagnetism and the weak nuclear forces have been shown to be two aspects of a single electroweak force.
Electromagnetism is a long-ranged force that is relatively strong, and therefore describes almost all phenomena of our everyday experience—phenomena ranging all the way from lasers and radios to the structure of atoms and the structure of metals to friction and rainbows.
One of the main effects of the strong force, is that it tightly holds two protons together in the Helium nucleus, despite their tremendous repulsion.

 Weak nuclear force - Wikipedia, the free encyclopedia
The weak nuclear force or weak interaction is one of the four fundamental forces of nature.
Although the weak nuclear force used to be described by Fermi's theory of a contact four-fermion interaction, today we know that it is mediated by the W and Z bosons.
The Standard Model of particle physics describes the electromagnetic force and the weak nuclear force as two different aspects of a single electroweak force, the theory of which was developed around 1968 by Sheldon Glashow, Abdus Salam and Steven Weinberg (more at W and Z bosons).

 [No title]   (Site not responding. Last check: 2007-11-05)
The strong nuclear force or strong interaction is a fundamental force of nature which affects only quarks, antiquarks, and gluons.
This force is responsible for binding quarks together to form hadrons (including protons and neutrons), and the residual effects also bind these neutrons and protons together in the nucleus of the atom.
Particles can only exist if their total color is neutral, meaning that they can either be composed of a red, green and blue quark (such a particle is called a baryon; protons and neutrons are examples), or of a quark and an anti-quark having the corresponding anti-color (such a particle is called a meson).

 Paradoxes Resolved, Origins Illuminated - Strong and weak nuclear forces in Meta Model
The force between the quarks within the nucleons is thought to be directly proportional to some function of r (probably something like r^n, with n being a positive number).
It seems that it is not the "real" strong nuclear force, but only a residual "side effect" (mediated by quark-antiquark pairs called mesons) of the strong nuclear force acting between the quarks (mediated by gluons, the gauge bosons of the strong nuclear force).
So, in summary, the strong nuclear force between the quarks seems to be in a direct relationship to some function of distance, while the residual strong interaction between the nucleons seems to be an inverse exponential force.

One of the four fundamental forces, the electromagnetic force manifests itself through the forces between charges (Coulomb's Law) and the magnetic force, both of which are summarized in the Lorentz force law.
The electromagnetic force is a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force.
The discovery of the W and Z particles in 1983 was hailed as a confirmation of the theories which connect the weak force to the electromagnetic force in electroweak unification.

All three particles are bound together by "the glue" of the strong nuclear force, and the protons are separated a little bit so the the repelling electric force has a smaller effect.
Here's the reason presented in your textbook: even though the nuclear force between the nucleons is strong, it acts only over a very, very, very tiny distance.

As deduced by the Unit Particle of Matter Substructure Theory, the tripolar color charge of the strong nuclear force is caused by the energy composing a quark being bound in a closed loop rotation about a quark triplet unit particle of matter substructure.
The strong nuclear force is a manifestation of electromagnetic force in which the distances involved between centers of electrical charge are within the structure of quarks as opposed to the distances between the centers being the distances of atomic nuclei and electrons.
The SU(3) symmetry associated with the strong nuclear force is proposed to be caused by the triplet unit particle of matter substructure proposed for the quarks.

The strong force is strictly an attractive force which acts between nucleons (protons and neutrons).
This is the force that overcomes the repulsive force within an atom due to the electromagnetic force and holds the nucleus together.
The strong force actually acts between quarks, and it's the residual strong force (similar to the residual electromagnetic force) that causes nucleons to attract.

If nuclear electrons and hyasis were not the case then a neutron inside a nucleus would not have the tendency to become protons and back to neutrons and vice versa, but rather instead remain their original identity as a proton or neutron and not flip back and forth.
That explanation is this: the strong nuclear force is the result of the neutrons being nuclear electrons and protons where the nuclear electrons are shared by all of the protons of the nucleus.

Two new forces are introduced when discussing nuclear phenomena: the strong and weak interactions.
The strong force, which we generally call the nuclear force, is actually the force that binds quarks together to form baryons (3 quarks) and mesons (a quark and an anti-quark).
On the other hand, because the exchange particles for the strong and weak forces have a large mass, the force associated with them is zero outside of a short range.

 String Theory of the Strong Nuclear Force   (Site not responding. Last check: 2007-11-05)
The subject of string theory arose in the late 1960's in an attempt to describe strong nuclear forces.
This approach to the description of strong nuclear forces was a quite active subject for about five years, until it was abandoned because it ran into various theoretical difficulties and because a better theory came along.
Another important development during this period (in 1971) was the discovery that to incorporate a class of elementary particles called fermions (electrons and quarks are examples) string theory requires a two-dimensional version of supersymmetry.

This is the force that acts at small distances within an atoms nuclei and maintains the stability of this nuclei in spite of their tendency to fly apart because of the Coulomb repulsion due to similar charged particles.
It is the exclusive force between electrons and neutrinos, but the same force (albeit much weaker than the electric or strong nuclear force) exists even between two protons.
However, at a longer distances both the nuclear forces are reduced to zero, and only the electrostatic and the gravitational forces remain of importance.

Protons and neutrons are made of smaller particles (quarks) that not only have electrical charges but also have "color": red green and blue (they aren't actually real colors as a quark is much smaller than even the wavelength in blue light so the terms are just a convention everybody uses).

Nuclear reactions involve changes in the nuclear binding energy, which is why nuclear reactions give you much more energy than chemical reactions; those involve changes in electron binding energies.
